Bile duct obstruction is a blockage in the tubes that carry bile from the liver to the gallbladder and small intestine. In serious cases, the common bile duct can be surgically moved so that it empties further down the small intestine.
It contains a mix of products such as bilirubin, cholesterol, and bile acids and salts. Bile ducts are drainage pipes that carry bile from the liver to the gallbladder and from the gallbladder to the small intestine. A variety of diseases can affect your bile ducts. All block the bile ducts in some way, which is why the various diseases cause similar symptoms. Gallstones are the most common cause of blocked bile ducts. Stones typically form inside the gallbladder and can block the common bile duct, the drainpipe at the base of the liver. If the duct remains blocked, bilirubin backs up and enters the blood stream.
